The redox properties of sulfite ion has been examind using cyclic voltammetry in acetonitrile solvent at the surface of gold, pelatin and glassy carbon electrodes. It has bben found tha, sulfite ion exhibits two electron oxidation peak with EC’ mechanism. A novel chemically modified electrode containing Prussian blue complex and multi wall carbon nanotubes (MWCNs) was achieved on the surface of...

As far as is known, the pigment Prussian blue was synthesised for the first time in Berlin in the early 1700s. It is commonly assumed that the pigment was not used in paintings before the 1720s. The presence or absence of this pigment is often used to answer questions concerning the dating and authenticity of art objects from the 18th Century. For the very first time, a large collection of Fren...

Prussian Blue (ferric hexacyanoferrate (II)), discovered accidentally in 1706 in Berlin by Johann Jacob Diesbach (1) and Johann Konrad Dippel (2), remains an intensively investigated material. Currently, more than 200 scientific publications with Prussian Blue as a research subject are published annually. Johann Leonhard Frisch (see below) and Diesbach produced Prussian Blue in the years follow...

INTRODUCTION Many investigators report that Prussian blue is effective on removing radiocesium from the body. However, we does not agree with the results obtained from the animal experiments, because administration methods on Prussian Blue administration used in these experiments, e.g., dose, route, initial time, resulting in superior effects are marked different from the conditions in the huma...

CONTEXT Prussian blue, ferric hexacyanoferrate is approved for (oral) treatment of internal contamination with radioisotopes of cesium or thallium. Cyanide makes up 35-40% of Prussian blue's molecular composition; thus, cyanide may be released during transit through the digestive tract under physiological pH conditions. OBJECTIVES The purpose of this study is to assess the long-term stability...
